DP10586 Optimal Monetary and Fiscal Policy in an Economy with Inflation Persistence

This paper studies a simple New-Keynesian model of fiscal and monetary policy coordination when the policymaker acts under commitment. With a New Keynesian Phillips curve it is optimal to control inflation only through the use of monetary policy. But, when price-setters use a Steinsson (2003) Phillips curve, fiscal policy plays an active role, enabling a greater degree of consumption smoothing.
